To' all whom it may concern:

Be it known that I, ANDREW E. MARK- WELL, a citizen of the United States, residing at Fort lVorth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Matrix Broach- Molding Devices, of which the following is a specification.

My invention relates to matrix molding devices for use in linotype or intertype or line casting machines, and the object is to provide devices for use in combination with matrix molding devices for molding holes of predetermined design through the beveled faces of type high cross rules at right angles The purpose of this construction is to prepare cross-rules which are adapted to break in the cross-lines at the point of crossing' Another advantage sought is to prechines without preparing new designs of *machines. "will be fully explained in the following de- --'.drawings which form a so Other objects and advantages scription and more particularly pointed out "in the claims.

Reference is had to the accompanying part of this application.

Figure 1 is an edge view or plan view of a matrix, showing the location of the improvements mounted therein. Fig. 2 is a side elevation of a matrix, showing the location of the improved forming devices. Fig. 3j-- is a side elevation of a matrix, with a part of, the inclos ing plate broken away to expose the forming devices. Figs. 4. and 4 are respectively a side elevation and an end elevation of one of the hole forming devices. Fig. 5 shows a side and an end elevation of "a slug, the side elevation showing the hole .fthrough the cross-rule.

i Similar characters of reference are'used to indicate the same parts throughout the several views.

A matrix block 1 is provided with a plate 2 which may be riveted to the block 1. Camties 9 are formed in the block 1 and forming devices 3 and 4 are pivotally mounted in the cavities and these formers have beveled ends 5. The ends 5 terminate in close proximity to each other and practically against each print cross-lines without any curedat 13 in the block 1 and press outwardly against the shoulders 10 so that the formers 3 and 4 are held yieldingly in their normal positions and will yield to the positions of the dotted outline in Fig. 3 to allow the removal of the casting I or FORT WORTH, EVANS, or.

or slug through the rule of which the hole has been cast. When the slug is drawn away from the matrix, the partso of the formers will be drawn outwardly by the slug and as soon as released, the

he slugs can .thus be formed with holes 8 through the rules 11 on the slugs. The rules on the slugs may be of any suitable design formers will be forced back within the block 1 in their normal positions.

provided they are type high. The holes 8 i should conform in cross-section'to the crosssection of the rule which is to be thrust through the holes 8. j

The matrix 1 and the plate 2 have cross grooves 18 through the top or upper part leading toward the forming devices 31 and 4 which have the'beveled surfaces 55.

What- I claim, is 1. Matrix molding devices comprising a body provided with longitudinal cavities in the edge thereof, a pair of forming devices mounted in said cavity and having the outer surfaces flush withthe edge of said body and having bearings for pivot bolts, pivot forming devices in said cavity, and springs for drawing said form- 'ing devices back into said cavity.

bolts holding said 2. Matrix molding devices comprising a body having longitudinal'cavities therein in one edge,'a pair of-forming devices pivotally mounted in said cavities and having their meeting ends triangular in cross-section and having extensions beyond the pivotal connections, and springs bearing against "the undersides of said extensions.

3. Matrix molding devices having a pair of forming devices pivotally mountedtherein and having openings extending inwardly lot toward said forming devices and springs holding said forming devices normally within said matrix.

4. Matrix molding devices comprising a matrix, forming devices having beveled under surfaces and pivotally mounted in said matrix and having backwardly extending shoulders, and springs attached to' said matrix and engaging said shoulders to hold said forming devices normally Within said matrix.

' Matrix molding devices having a matrix provided with a longitudinal cavity therein, forming devices having beveled under surfaces attheir "meeting pivotally mounted in said cavity and having backwardly extending shoulders, and springs attached to said matrix and pressing outwardly against said shoulders, s'aid matrix-having grooves extending through the sides to said forming devices.

In testimony whereof, I set the presence oi two Witnesses, of August, 1913.
